/*
Optical Heart Rate Detection (PBA Algorithm) using the MAX30105 Breakout
By: Nathan Seidle @ SparkFun Electronics
Date: October 2nd, 2016
https://github.com/sparkfun/MAX30105_Breakout
This is a demo to show the reading of heart rate or beats per minute (BPM) using
a Penpheral Beat Amplitude (PBA) algorithm.
It is best to attach the sensor to your finger using a rubber band or other tightening
device. Humans are generally bad at applying constant pressure to a thing. When you
press your finger against the sensor it varies enough to cause the blood in your
finger to flow differently which causes the sensor readings to go wonky.
Hardware Connections (Breakoutboard to Arduino):
-5V = 5V (3.3V is allowed)
-GND = GND
-SDA = A4 (or SDA)
-SCL = A5 (or SCL)
-INT = Not connected
The MAX30105 Breakout can handle 5V or 3.3V I2C logic. We recommend powering the board with 5V
but it will also run at 3.3V.
